Heterocurious is a term for someone who is primarily attracted to the same gender or similar gender(s), but shows interest in or is considering experimenting with having relationships with the "opposite" gender or dissimilar gender(s) or genders unlike one's own.[1] It may also be considered a term for someone who is questioning whether or not they're heterosexual or duaric.
It can be a subset of bicurious. Its counterpart is homocurious.
